  • Publication number: 20230407206
    Abstract: A method of in home preparation of a fabric conditioner, wherein an aqueous concentrated fabric conditioner comprising: a. 10 to 50 wt. % ester linked quaternary ammonium compound; and b. Non-ionic surfactant; is mixed with water to produce an aqueous fabric conditioner composition, wherein the ratio of non-ionic surfactant to fabric softening active is 1:10 to 1:40 by weight and the ratio of concentrated fabric conditioner composition to water is 1:20 to 1:1 by weight. A method of producing the concentrated aqueous fabric conditioner, said method comprising the step of: a. Mixing a fabric softening active and non-ionic surfactant to form a pre-mix at a temperature above 50° C.; b. Adding the premix to an aqueous composition comprising water.

  • Patent number: 6451752
    Abstract: A method for bleaching stained fabrics is provided by pretreating the stained fabric, before washing, with a pretreatment composition that comprises a ligand that forms a transition metal complex as bleach catalyst, the complex catalysing bleaching of stains by atmospheric oxygen. The pretreatment composition preferably comprises an iron complex comprising the ligand N,N-bis(pyridin-2-yl-methyl)-1,1-bis(pyridin-2-yl)-1-aminoethane. One or both of the pretreatment composition and the wash liquor are substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system. The pretreatment provides improved or broader stain profile bleaching.

  • Patent number: 6302921
    Abstract: A method for bleaching stained fabrics is provided by washing a stained fabric in an aqueous wash liquor in the presence of a wash additive that comprises a ligand that forms a transition metal complex as bleach catalyst, the complex catalysing bleaching of stains by atmospheric oxygen. The wash additive preferably comprises an iron complex comprising the ligand N,N-bis(pyridin-2-yl-methyl)-1,1-bis(pyridin-2-yl)-1-aminoethane. One or both of the wash additive and the wash liquor are substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system.
